Agricultural residues as feedstocks for biofuels production
A wide range of agricultural residues (e.g. corn stover, straw, etc) can be used for production of second generation biofuels. Such biofuels are generally considered sustainable as they use waste materials from food crop production, and do not compete with food crops for land.
A number of conversion technologies can be used with agricultural residues. For example, conversion of:
Wheat straw or corn stover to cellulosic ethanol via pretreatment, hydrolysis and fermentation
